Wishloop is optimised to work across most common browsers, but due to minor differences between them all, there's no way we can get it perfect!
We recommend Chrome as the browser of choice, Firefox as a second choice.
We have had some unresolveable issues with Safari, particularly relating to mobile views.
Internet Explorer is largely compatible, except that it will not accept 'Exit intent' Pop-ups. Given the drastic reduction in IE users since the Windows 10 Switchover, and the fact that Microsoft are no longer updating IE, there are currently no plans to update Wishloops' level of compatibility
